Video: Simulating atmospheric reentry in a plasma wind tunnel
Wednesday, 23 June 2021 13:23Simulating the burn-up during atmospheric reentry of one of the bulkiest items aboard a typical satellite using a plasma wind tunnel.
This Solar Array Drive Mechanism (SADM) has the essential task of keeping a satellite's solar wings trained on the Sun, maintaining mission operations.
But its bulky nature presents a problem in terms of space debris guidelines. When a spacecraft reenters on an uncontrolled basis, the spacecraft operator has to prove that the on-ground casualty risk posed by its satellite is lower than 1 in 10 000.
So last year SADM manufacturer Kongsberg Defense & Aerospace (KDA) started an investigation supported by ESA, Hyperschall Technologie Göttingen GmbH (HTG) and the German Aerospace Center (DLR) to demonstrate the 'desmisability' of one of its satellite products.
They began by modeling such a reentry using ESA's dedicated SCARAB (Spacecraft Atmospheric Reentry and Aerothermal Break-up) software and comparable resources, tweaking the SADM by switching one screw to lower-melting-point alumimium to promote an earlier, higher-altitude breakup.
